01Measure the garment, not the label
Compare chest width, body length, shoulder and sleeve measurements with a garment you own. Size letters vary by seller and cut. Ask for a warehouse measurement only when the available photo or chart does not answer the fit question.
02Inspect construction and decoration
Check seams, ribbing, hood shape, pocket alignment, drawstrings, print edges and embroidery placement. Lighting can shift colour, so use photos to identify large mismatches rather than promise an exact screen-to-fabric match.
03Plan for bulk
Fleece and heavy knits can occupy more parcel space than their product price suggests. Compare packed dimensions, avoid compression for items that could be damaged by it, and use the live route quote after consolidation.
